所谓并列句，就是有并列连词连接两个或两个以上的简单句而成的句子。

所谓复合句，就是除主句外还包括一个或一个以上从句的句子。

注意：短句子不等于简单句，长句子不等于复杂句。所谓简单句是指就只有一个主干的句子。

注意：汉语中可以用逗号分隔两个完整的句子，英语中绝对不可以。

英语里面，只要出现两个完整的句子，之间绝对不能出现逗号，而必须有连词连接，或者把其中一个句子化简为分词短语或不定式短语。

单一连词：and、or、but，此种连词可以连接对等的句子，或连接句子中任何对等的成分。

I had just lost 50 yuan and I felt very upset.烦恼

The police had a difficult time, but they were most amused. 有趣

注意：or连接句子的时候，通常用于祈使句后面，翻译为否则。

Obey your boss or you will be fired.

Don’t cheat at exams or others will despise you.

Give me liberty or give me death.

祈使句就是你命令他去做某一件事，加上would you please会显得有礼貌。

A young man and a young woman were sitting behind me.连接主语。

I visited museums and sat in public gardens.连接谓语，相当于连接两个句子，省略了第二个句子的主语。

I entered the hotel manager’s office and sat down.

注意：连接谓语的时候，只要助动词相同，即可省略助动词，谓语动词相同的也可以省略。

Mary is very happy but John (is) very miserable.

And 也可以表示“然后”，“但是”，“那么”，“则”的意思。
